This paper describes an active control system intended to minimize the vertical vibrations transferred from the seat to a driver in a vehicle. This system controls mechanical properties such as the spring constants and damping coefficients of the seat cushion by using an optimized algorithm that comprises vibration analysis and an optimization method. To estimate an optimized algorithm, we investigate reduction rates of the vertical vibrations on the head, the body, the thigh and the shin using a vibration analysis based on a model for the seat-occupant system during the seat cushions that control the mechanical properties are changed. From the results, it shows the relationships between the vertical accelerations at each part of the driver and the mechanical properties of the seat cushion optimized. In conclusion, the reduction rates of the vibrations on the head, the body, the thigh and the shin were clarified at each frequency band.
